In addition, the lever armcarries a spring that extends parallel over the top sideof the arm and terminates over a hole in the lever tungsten contact mounted upon this spring extendsthrough the hole in the arm and engages with anothertungsten contact that is also adjustably mounted in thesame insulated plate with the silver contact. The ten-sion of the tungsten contact carrying spring is such thatit exerts a pressure downward. The adjustment of theinterrupter contacts must be such that the silver con-tacts separate before the tungsten contacts do. When the cam strikes the fibre bumper of the leverarm it first lifts the arm and therefore breaks the con- FIBER BUMPER.

The break between thetungsten contacts occurs a very short time afterward—as soon as the bend of the contact carrying spring istaken up. The result of this sequence of contact separations issuch that if the tungsten contacts should be oxidized tosuch an extent at starting that the high resistance ofthe oxide makes the magneto inoperative, the completedcircuit through the silver contacts which do not oxidizereadily will allow the magneto to function and the sparkwill be produced when the silver contacts separate. Theengine will therefore start up on the action of the silvercontacts. After a few revolutions of the engine the mechanicalaction between the tungsten contacts of the interrupter LATCH CATCH 2.
